Abstract: Compositions and methods for improving transperitoneal oxygen uptake during peritoneal ventilation for extrapulmonary oxygenation of an organism or individual organs in preferably life-threatening case of need, such as pulmonary failure or circulatory shock, are disclosed. Such deficiencies can be addressed by transperitoneal administration of oxygen via a gas introduced into the abdominal cavity. A liquid, preferably aqueous, composition including an oxygen carrier such as hemoglobin is used, which, surprisingly, is capable of increasing the effectiveness of the diffusion of the oxygen administered by a one-time or repeated filling or continuous flushing of the abdominal cavity. An oxygen carrier, such as hemoglobin or derivatives thereof, is used for the manufacture of a composition for improvement of the diffusion of oxygen (gas) introduced into mucus layers of the peritoneum, preferably to enhance the diffusion of oxygen in transperitoneal ventilation.
